300-365 Question #145: Real Exam Question with Answer & Explanation

The correct answer is A: coefficient based on SNR. AWPP calculates an 'Ease' metric using the raw SNR, an SNR-derived coefficient, and a hop value penalty to determine the optimal backhaul path to the root AP.

Question

Which three values make up the combination for Ease calculation in AWPP path selection? (Choose three.)

Options

Acoefficient based on SNR
Blink budget
CRx sensitivity
Dgain
Ehop value
FSNR

Explanation

AWPP calculates an 'Ease' metric using the raw SNR, an SNR-derived coefficient, and a hop value penalty to determine the optimal backhaul path to the root AP.

Common mistakes.

B. Link budget is a general RF engineering planning tool used to verify theoretical path feasibility but is not one of the discrete inputs in the AWPP Ease formula used during runtime path selection.
C. Rx sensitivity is a fixed hardware specification describing the minimum detectable signal power of a radio and is not a dynamic variable factored into the AWPP Ease calculation.
D. Antenna gain is a physical hardware characteristic used in link budget design calculations but is not a separate component included in the AWPP Ease metric formula.
